RADIO FREQUENCY CIRCUIT AND COMMUNICATION DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18748506 titled 'RADIO FREQUENCY CIRCUIT AND COMMUNICATION DEVICE
The abstract describes a radio frequency circuit capable of transmitting signals in two different frequency bands simultaneously.
- The circuit includes a first power amplifier supporting a first power class and a second power amplifier supporting a higher power class for a transmission power exceeding that of the first power class.
- A switch with a common terminal connected to a first antenna terminal, a first terminal, and a second terminal.
- A first filter connected between the first power amplifier and the first terminal, with a passband covering a portion of the first frequency band.
- A second filter connected to the second power amplifier and the second antenna terminal, with a passband covering a portion of the second frequency band.
- A third filter connected to the second terminal.
Potential Applications: - This technology can be used in multi-band communication systems where simultaneous transmission in different frequency bands is required. - It can be applied in wireless communication devices that need to operate in multiple frequency bands efficiently.
Problems Solved: - Enables efficient simultaneous transmission in multiple frequency bands. - Provides a compact solution for multi-band communication systems.
Benefits: - Increased flexibility in communication systems. - Enhanced transmission capabilities in diverse frequency bands.
